After moving into a new home and giving birth to her first child, a woman worries that a supernatural force is haunting her child’s nursery, and has corrupted her husband into a creature intent on harming them both.

Emma is excited to start a family in her new home, but after her child’s birth she finds her world turning upside-down. The infant cries like it’s scared of something, or someone, and Emma’s sleepless nights quickly drive a wedge between her and her husband, who seems uncharacteristically detached. When Emma begins to see strange things in the house, the line between reality and fantasy blurs and her grasp of what’s real and what’s not becomes even more clouded. Is something unnatural haunting the nursery? And what if it also affected her husband, who ventured up into the attic when they first arrived...

Inspired by the works of Shirley Jackson and Ira Levin, Celine Loup’s The Man Who Came Down the Attic Stairs weaves a tale of horror and suspense that captures the isolation of postpartum depression, while exploring the very real fears associated with new motherhood.
